These pillars help cultivate spiritual understanding and insights to reduce one's suffering and dissatisfaction in life. The four pillars of knowledge are Viveka, Vairagya, Shat-sampat and Mumukshutva.

Yoga manifests itself as four major paths, namely Karma Yoga, Bhakti Yoga, Rāja Yoga and Jñāna Yoga. These four paths are like the branches of a tree or tributaries of a river. They all have the same source and resting place. In essence, they are all the same.

Concept. According to Krishna in the Bhagavad Gita, Karma yoga is the spiritual practice of "selfless action performed for the benefit of others". Karma yoga is a path to reach moksha (spiritual liberation) through work.

Also known as Gyana Yoga, Jnana Yoga is defined as the practice of shedding the ego and gaining knowledge of the true Self through self study and analysis. With this deep awareness of the 'Self', you are able to understand the difference between what is real and unreal.
